Use when a developer is building, analyzing, or shipping on Flow (Cadence or Flow EVM) and needs an ecosystem tool: on-chain analytics, metrics, a query, or a dashboard (Dune); a Flow EVM RPC endpoint, node access, or reading chain state from an app (Alchemy); or swapping tokens, adding liquidity, getting a price quote, or integrating a DEX (PunchSwap / KittyPunch). Routes the builder to the right Flow ecosystem integration and supplies how to call it (MCP server, docs, or on-chain contract). Triggers on requests like "building on Flow and need a tool for X", "how do I get Flow on-chain data or a dashboard", "what should I use to query Flow", "Flow EVM RPC or node provider", "how do I swap or add liquidity on Flow", "integrate a DEX on Flow", or "is there a Flow tool for X". Not for non-Flow chains, and not for Cadence language correctness.
Comprehensive guide for writing correct, secure, and idiomatic Cadence smart contract code on the Flow blockchain. Covers language fundamentals (resources, contracts, transactions, interfaces, accounts, references, imports), access control and entitlements, capabilities, pre/post conditions, security best practices, anti-patterns to avoid, and proven design patterns.
